1、 Annealing processability
The spheroidizing annealing temperature range is wide, the annealing hardness is low and the fluctuation range is small, and the spheroidizing rate is high.
It has low hot forging deformation resistance, good plasticity, wide forging temperature range, and low tendency of cold forging cracking and precipitation of network carbide.
3、 Oxidation and decarburization sensitivity
During high temperature heating, the oxidation resistance is good, the decarburization speed is slow, the heating medium is insensitive, and the tendency to produce pitting is small.
Large cutting parameters, low tool wear and low surface roughness.
After quenching, a deeper hardened layer can be obtained, which can be hardened by using a mild quenching medium.
The relative loss of the grinding wheel is small, the burn free limit grinding amount is large, and the grinding wheel is insensitive to the quality and cooling conditions of the grinding wheel, so the grinding damage and grinding cracks are not easy to occur.
It has uniform and high surface hardness after quenching.
8、 Quenching deformation cracking tendency
Conventional quenching has small volume change, slight shape warping and distortion, and low tendency of abnormal deformation. Conventional quenching has low sensitivity to cracking and is insensitive to quenching temperature and workpiece shape.
